In search of closed-type headphones with crisp and clear neutral sound

Well, I tried to tell everything right from the start I need your recommendations on some quality headphones. These have to be:- closed-type headphones with classic look (I'll point out Sennheiser PX 360 for reference)- neutral sounding, with warm bass and clear & crisp mids and highs (is this too much to ask for? ). The upper limit of the freq. response should be at least 22000 Hz- price up to $150, but don't hesitate to recommend some good phones even if they're a bit over that price.
I'll listen to my mp3 player with them, so the more comfortable and light weight - the better. The cable shouldn't be too long but has to be durable.
Please, help me out!
